[dts] Question regarding to self.core_config in TestSuite_l2fwd.py and in other test modules

[Kevin Wilson]

Hello,
I want to clarify one point:
we have in
http://dpdk.org/browse/tools/dts/tree/tests/TestSuite_l2fwd.py#n58
...
self.core_config = "1S/4C/1T"
...

We have also some similiar core_config in other DTS tests modules.

1S stands for "one socket".

Is this expected to work also on a machine which has 2 sockets ?  or
should we change it to
...
self.core_config = "2S/4C/1T"
...

so it will work ?

Regards,
IB

Hi Kevin,
"1S/4C/1T" mean return core list with the first four physical cores on the first socket. Definitely this configuration should be workable on 2S system.
Similarly, "2S/4C/1T" mean return core list with the first physical cores belong to first and second socket.
When developing the test suite, core requirement has been determined. So you do not need to change the configuration.
Suites should check returned core list and alert when cores can't fulfill the requirement.

Thanks,
Marvin
